Victor,
We are using a Dell XPS system with Intel 82801FR SATA RAID Controller. We too experience the utterly frustrating failure message when attempting to run an ASR backup.
So your identification of the issue, at least in our case, would appear to be correct. We are currently using version 4.0.0.6211 (03/23/2004) of the drivers. I'm going to check Intel's site now and will post whether there are any BIOS flashes or updated drivers available. If not, is the only solution to install a different RAID controller?
Thanks,
Michael
